Disconnect both of the harnesses from the CHTO-01.

Remove the cove from the CHTO-01 by squeeezing the sides of the
cover to release the clips.

Locate the potentiometer on the circit board.
See Figure A.

Taking a small flat headed screwdriver, turn the potentiometer counter-
clockwise to lower the input level going to the factory amplifier.

After making the adjustment, replace the cover and reconnect wire
harnesses.
